l o R EN A. Ross ATTORNEYS United The present invention relates toimprovements in a socket wrench turning device. It consists of thecombinations, constructions, and arrangement of parts, as hereinafterdescribed and claimed.

In the automotive art, it is a conventional practice to employ studs forremovably securing wheels in place. These studs are difficult to remove,especially from the heavier types of wheels, due to rusting of the studsand accumulation of corrosive substances. Moreover, these studs must beapplied tightly; consequently, considerable force must be used inremoving the studs.

Socket wrenches are employed for removing these studs, and mechanicsoften insert a length of pipe through an opening in the wrench in orderto obtain the necessary leverage. However, thepipe bends frequentlybefore the stud will loosen.

In my United States Patent No. 2,577,157, issued on December 4, 1951on-a Socket Wrench Turning Device, I show a section of a link chain witha wrench-engaging rod at one end and a handle at the other end. The rodis insertable into a transverse opening provided in the socket in thesocket wrench, and then the link chain is wound around the wrench. Aswinging'of the handle causes the rod to rotate the wrench for looseningthe wheel nut. However, the cost of the link chain made the device tooexpensive to manufacture and sell.

In the present invention, the socket wrench turning device issimplified. In place of the link chain, I provide an elongated leveragecasing that has a transverse opening near one end, which is adapted toreceive a socket wrench, and has a leverage rod at its other end thatextends substantially at right angles to the length of the casing inorder that the operator may apply the desired leverage in loosening ortightening the sleeve-like bolts and the nuts of the truck wheel.Moreover, a pin is slidably carried by the casing, and it is mounted inthe area lying between the socket Wrench receiving opening and theleverage rod. Therefore, the distance between the casing opening and theleverage rod serves two purposes: one, to create the necessary leveragedistance between the leverage rod and the socket wrench; and, two, toprovide space to house and protect the pin that is designed to enter abore in the socket wrench.

A further object of my invention is to provide a device of the typedescribed, which is simple in construction, durable and efficient forthe purpose intended. It does not take up much space, and can be carriedas a tool for attaching the truck wheel or removing the wheel from thetruck axle.

Other objects and advantages will appear as the specification proceeds,and the novel features of the invention will be set forth in theappended claims.

While I have shown only the preferred form of my invention, it should beunderstood that various changes, or modifications, may be made Withinthe scope of the appended claims without departing from the spiritthereof.

Detailed description In carrying out my invention, I illustrate atransverse cross-section of a pair of standard dual wheels in Figure 1,which are designated generally at A and B. A series of sleeve-like boltsC are used for holding the innermost wheel B in place, and these boltsare threaded both internally and externally as shown in Figure 1. Thesesleeve-like bolts arescrewed upon studs C and have enlarged double-coneheads Id at their inner ends that bear against walls of openings formedin the wheel B through which the studs C extend. The outer ends of eachof these sleeve-like bolts is fashioned with a square head 1. It will benoted that a hexagon nut D is screwed upon the external threads of eachof the bolts C so as to bear against the outer wheel A so as'to hold thelatter in place. The studs C are anchored to the flange E of the wheelhub, as clearly shown in Figure 1. Thus, the sleeve-like bolts C holdthe inner wheel B in place, while the nuts D are utilized for holdingthe outer wheel A in place. The parts thus far described areconventional.

It will be noted that a conventional socket wrench F is shown in Figures1 and 2. The right-hand end of this wrench is formed with a socket Gtherein, with the side walls 2 of this socket forming a hexagon that isadapted to receive the hexagon nuts D. The left-hand end of the wrench Fis provided with another socket H, and its side walls 3 define a squaredesigned for receiving the square ends I of the sleeve-like bolts C. Theouter surfaces enclosing the sockets G and H are made cylindrical inshape as indicated at 4 and 5,.respectively. These cylindrical ends 4and 5 serve the purpose hereinafter described. The socket wrench isfurther provided with a' transverse bore 6 which is placed near thehexagon socket G, while a second transverse bore 7 is placed near thesquare socket H. The parts of the socket wrench F are conventional andform no part of my invention, except insofar as they cooperate with theparts now to be described.

In Figure 1, there is shown a one-piece elongated stand J, which has oneend 8' arranged to rest upon the ground K. The stand, when in thisupright position, has a number of steps or ledges 9 and the top step hasbeen illustrated as rotatably supporting the outer cylindrical end 5 ofthe wrench F. There are usually eighthexagon nuts D to be loosened, whenfreeing the outer truck wheel A from the sleeve-like bolts C. The nuts Dthat are on the upper half of the wheel A can be loosened by the wrenchF, with the cylindrical end 5 resting on the proper step 9 which isdisposed at the correct height for supporting the wrench. The stand Imay be inverted, when the nuts -D on the lower half of the wheel A areto be loosened. This will bring the end 10 of the stand I into contactwith the ground K, and cause a second group of steps 1:1-to faceupwardly and different ones of these will be used for supporting theouter end 5 of the wrench F, as the various nuts D are loosened.

The socket wrench turning device is indicated generally at L in Figures1, 3 and 4 of the drawings. This device comprises a leverage casingwhich has two elongated plates M of the same size and these plates arespaced a predetermined distance and lie parallel to one another. It willbe observed that three spacing members N, P and Q are placed between theplates M and are secured thereto for holding them together to form thecasing. The spacing members N, P and Q have aligned openings 12, 13 and14, respectively, for slidably receiving a pin R. The latter may bemoved by hand in either direction, and the pin is provided with a head15, which may be manually grasped for this purpose. A coil spring S maybe mounted on the pin R, with one end bearing against the spacing memberN, and the other end of the spring bearing against a stop 16 carried bythe rod R. This spring yieldingly urges the pin R in a direction tocause the end of the pin disposed opposite the head to enter the opening14 in the spacing member Q.

As clearly shown in Figure 4, the spacing members P and Q are arrangedon opposite sides of a wrenchreceiving opening 17 provided in each ofthe plates M. These openings 17 are aligned with each other, and theedges of these openings disposed nearest the outer surfaces of theplates M are chamfered, as at 17a, in order to make it easy to move thesocket wrench turning device L over the wrench F and have thecylindrical end 5 enter the openings 17.

At the end of the socket wrench turning device L opposite that of theopenings 17, I mount a leverage rod T. The latter has an end 18 receivedbetween the plates M, and this end is preferably welded or otherwisesecured to the plates M. The axis of the leverage rod T extendssubstantially at right angles to the lengths of the plates M. It will beobserved that a tubular or hollow leverage pipe or handle U has a borelarge enough to receive the exposed end of the rod T. The handle U maybe three or four feet long in order that the operator may exertconsiderable force in rotating the socket wrench F for either looseningor tightening the sleeve-like bolts C and the nuts D.

Operation Figure 1 shows the socket wrench F as being applied to one ofthe hexagon nuts D preparatory to loosening this nut. The Wrench turningdevice L has been applied to the cylindrical end 5 of the socket wrenchF, and the pin R has been moved into the bore 7 in the wrench. Theexposed end of the cylindrical end 5 rests on the top step 9 on theone-piece stand I. The handle U is mounted on the leverage rod T and thedevice is now ready to operate.

The handle U is swung for rotating the socket wrench F in acounterclockwise direction for loosening the hexagon nut D. When a halfrevolution is made by the wrench F, the pin R is withdrawn from theopening 7 to permit the handle U to be returned through a half circleswing, whereupon the pin R is again inserted into the bore 7. Anotherhalf circle swing in a counterclockwise direction is made to rotate thenut D through a similar arc.

Usually, only one or two swings of the handle U are necessary to freethe nut D to a point where the remainder of the turning to free the nutfrom the sleeve-like bolt C can be done by hand. Each nut D is loosenedin this same manner, and the different steps 9 and 11 are used on thestand I in order to keep the wrench F in substantially a horizontalposition. This will allow the outer wheel A to be removed.

When it is desired to remove the sleeve-like bolts C to thus permit theinner wheel B to be taken off, the wrench turning device L is appliedover the Wrench F as indicated by dot-dash lines in Figure 2. At thistime, the square socket H should face toward the wheel 'B, while thecylindrical end 4 is supported by the stand I The socket H is engagedover the square ends 1 of the sleeve-like bolts C, and the deviceoperated so as to remove these bolts from the studs C. When this hasbeen accomplished, the inner wheel B may be taken oft". The reversesteps are taken when tightening the sleeve-like bolts C and the nuts Dfor holding the dual wheels in place.
